Mid-American Gardener: radishes, pruning roses, black walnut trees, true yams pinewood nematodes

Horticulture expert Dianne Noland, special guest panelists Chuck Voigt, Nancy Pataky and David Robson discuss maximizing our radish crops, the best time to prune roses this year, starting an organic garden, how to check foliage for diseases and how black walnut tree roots produce a chemical that keep vegetable gardens from growing. Chuck Voigt shows a beautiful true yam and explaines that the yam is not only the #3 root crop but its also poisonous. It seems that the cyanide within the yam needs to be cooked out of it to be safe. Nancy Pataky demonstrated how to root out the pesky pinewood nematode and what your pine may look like when infected plus much much more.
